@ATEL QFFICE OSCILLATION METER.

Application tiled November 17, 1925, Serial No. 69,715, and in Germany February 2'. 1925.

This invention relates to an improved oscillation meter, of a similar kind to that protected by our ll. S. Patent No. 1.586,004 dated May 25th. 1026, said improved oscillation meter comprising essentially a light thin-walled casing` taking-up the oscillations to be measured and within which a heavy inert mass is suspended by springs while the oscillations occurring between said casing and the inert mass are perceptible by means of a measuring apparatus inserted between them.

According to the present invention, the inert mass forms a heavy case enclosing a supporting member or socket of light mass which is to take-up the oscillations to be measured, the measuring apparatus being inserted between said case and socket.

In the accompanying drawings; Figs. l and 2 are respectively a perpendicular central section through and a sectional plan view of, the improved oscillation meter, while Figs. 3 and l are respectively a perpendicular central section through` and a plan view of, a modification thereof.

Referring to Figs, l and 2 the heavy inert mass 03 forms the casing` for the oscillation meter, and it is suspended by means of tine perpendicular supporting springs 793 and radial springs 724 from a socket c3 of light mass which somewhat proiects therefrom at its lower end. with which it is placed upon the supporting base the oscillations of which are to be determined and measured. Said socket carries integral arms f3 with contact faces thereon` which directly7 act upon contact-pins e3 of the measuring apparatus 73 of any appropriate type. The latter is carried by, an integral cup Z4 of the caselike inert mass c3, or in any other appropriate way.

The caselike inert mass c3 is provided at the top and bottom with an annular cover c* and c5 respectively detachably fastened thereon b v means of screws c6, c7, the upper cover c4 having a glass sash therein to allow an inspection of the interior of the case from above.

A special advantage of the improved oscillation meter lies in the fact that, when lifting the apparatus from its supporting base. that is when the same is not in its position of use. the socket is, by action of the tine perpendicular springs 3, caused to bear directly upon the cover c5 so that for a transportation of the apparatus special fastening of the movable parts to each other is not necessary. Preferably. for transporting the apparatus. it is turned upside down. the fine perpendicular springs 793 lifting then the socket .3 and forcing the same also against the cover c5 of the inert mass 0', thus locking it thereon.

Referring' to Figs. 3 and 4: also in this example` the heavy inert mass CS forms the casing for the oscillation meter, and it is suspended by means of tine perpendicular supporting springs 715 and radial springs 7)6 from a socket f1.4 of light mass, of which in this case the upper surface is cup-shaped for a reception of the measuring apparatus (75 thereinq while the contact-pins et of the latter are directly in slight contact with the inner walls of the caselike inert mass es. This arrangement has the same special advantage as that above explained with reference to that illustrated in Figs. 1 and 2.

Owing to the casing c3 or cS being rather strong, a very handv and compact apparatus that cannot easilv he destroyed, is created.

Obviously` and to be understood without further illustration` the measuring apparatus can be formed as or be replaced by a recorder for registering the oscillations.

That we claim., is:

l. An oscillation meter comprising, in combination. a caselike heavv inertmass. a socket of light mass enclosed by said inert mass and adapted to take-up the oscillations to be measured.` the lower end of said socket projecting somewhat from said caselike inert mass, tine perpendicular and radial supporting springs.intervening between said inert mass and said socket` a measuring apparatus inserted between said inert mass and said socket, and contact-pins on the latter creating a slight contact between said socket and said incr mass. substantially as setforth.

2, An oscillation meter as specified in claim 1, in which said measuring apparatus is carried by said socket, substantially as not in its position of use, substantially as set forth. set forth.

3. In an oscillation meter as specified in In testimony whereof We have hereunto 10 claim l, an annular' fixed cover for said easeset our hands.
